Diammonium phosphate (DAP) is a common phosphorus source used on soybean.
New university research highlights the need for sulfur (S) management on soybean due to higher grain yields and lower atmospheric deposition. This data also emphasizes the need for availability during both vegetative and reproductive growth (See Figure 1).
MicroEssentials® S10® supplies multiple nutrients fused into one nutritionally balanced granule, providing uniform nutrient distribution, improved nutrient uptake, season-long S availability and increased yield.
Crop: Soybean (Glycine max)
Locations: 12 trials - AR, IL, IN, MI, OH, ON, WI
Data Source: Field studies conducted by independent third-party researchers.
Experimental Design: Small-plot RCBD with 4 replications.
Cropping Conditions: All trials conformed to local cropping practices.
P Rate: 40 lbs P₂O₅/ac applied as DAP (18-46-0) or MicroEssentials® S10® (12-40-0-10S)
S Rate: 10 lbs S/ac from MicroEssentials® S10®
K Rate: As required by soil test
Application Timing: Spring Preplant
Application Method: Broadcast incorporated
Averaged across 12 trials in 2017-18, MicroEssentials® S10® increased soybean yield by 1.7 bu/ac over DAP.
Higher soybean yields achieved by using MicroEssentials® S10® demonstrates the value of uniform nutrient distribution, increased nutrient uptake, and season-long S availability (sulfate + elemental).
